Looks like the order they appear in is the correct order.
1. Question-wording bias
2. Under-coverage
3. Response bias
For number 1 the first arrow is the cell wall, the second is the membrane, and the last arrow would be the cytoplasm
For number 2 they are in distilled water Bc they are remaining the same and not shrinking up
For three draw the cells smaller salt water sucks the water out of them
For four they get smaller because the salt has a higher concentration making the water leave the cell. Once water has left the cell begins to shrink
True
Explanation:
Aqueducts are constructed channels for transporting water from one point to another.
- They were first constructed by the Roman to move water from hollow valleys and narrow areas.
- Today, aqueducts include canals, ditches, gutters, channels that are used to carry water.
- Aqueducts aids the movement of water from one place to another.
- Development of aqueducts by the Romans was seen as a great advantage in that civilization.

Answer:
Dihybrid cross
Explanation:
The punnet square is often used to solve problems involving two factors which are known as a dihybrid cross.
- Also, the punnet square is used for a single factor and this is known as a monohybrid cross.
- They show all genotypes that can result from crosses.
- A punnet square is used for statistically establishing the likelihood of a set of gene to form and dominate.
- It is made up of a square boxes which holds the genotypes formed.
The correct answer is: D) Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.
The motor neuron cell is connected to muscle cell via synaptic cleft, where neurotransmitter is released. The muscle side of this synapse is called motor end plate. Released neurotransmitter is acetylcholine and it binds to its receptor (ACh receptor) on the motor end plate. As it binds, ion channels open, and Na+ gets into the muscle cell. This event reduces the voltage difference between the inside and outside of the cell and causes depolarization which creates a wave through the entire muscle cell (its membrane-sarcolema). As a consequence, Ca2+ is released from the sarcoplasmic reticulum which will cause the contraction of the muscle cell.
